When we first started this project, Scott and I wanted to avoid using the more popular files as our weekly pick. I am going to break from that rule, because in face-to-face interaction I recommend this file to more customers than any other and think it needs to used more often.

Why use a style guide?

There are lots of somewhat arbitrary choices we make when coding: Should the variable be named numCatagories, or cat_num? How far should I indent? What should I name this function? By adopting a standard like the one in this document, you will know the answers to these question and make code that is written consistently.
